WILLIAM HARRIS, OF NEW YORK, N. Y.

AMALGAMATOR.

SPECIFICATION forming part of Letters Patent No. 272,544, dated February20, 1883.

' Application filed April 26, 1882. (No model.) i

To all whom. it may concern:

Be it known that 1, WILLIAM EDWARD HARRIS, of the city, county, andState of New York, have, invented a new and useful Improvement inAmalgamators, of which the following is a full, clear, and exactdescription.

Reference is to be had to the accompanying drawing, forming a part ofthis specification, and which is a sectional side elevation of myimprovement.

The object of this invention is to facilitate the separation of linegold from pulverized ore, and from black sands and other sands.

The invention is an improvement in the class ofapparatus in which astream of pulverized or granulated ore is projected into a bath ofmercury and the waste or refuse material carried oft bythe overflow ofwater which is constantly admitted into the bath. A

The improvement consists in the combination of parts, as hereinafterdescribed and claimed.

The amalgamating-pot is secured in an erect position upon the bottom ofan inclined sluice by bolts and tapered blocks, and is surrounded by acasing to confine the steam, as will be hereinafter fully described.

A represents the amalgamating-pot, which is made cup-shaped, and with afoot, B. The foot B rests upon the level upper side of a wedge-shapedblock, C, the inclined side of which rests upon the inclined bottom ofthe sluice D. The foot B is secured to the block 0 and the bottom of thesluice D by bolts E, a tapered block or tapered washers F being placedupon the lower side of the bottom of the sluice D to give the heads andnuts of the bolts E a square hearing.

The powdered ore or fine sand is fed into the pot A through the funnelG, which passes through a hole in the top of the casing H and extendsdown into or a little below the middle part of the potA. The tunnel G issupported by the casing H or a suitable frame. The upper part of thecasing H is made steam-tight, and its open lower end extends down to ornearly to the foot B, and is made larger than the said foot, so that theoverflow of the pot A can escape freely into the sluice D. The casingHcan be supported by bars attached to the sluice D, or by other suitablemeans.

I is a steam-pipe passing down through the center of the funnel G, andextending nearly to the lower end of the said tunnel. The pipe I isprovided with a valve, J, by means of which the discharge of steam isregulated and stopped, as may be required.

vVater is introduced into the flaring upper part of the funnel Grthrough a pipe, K, which. is provided with a valve, L, so that theinflow of water can be regulated and stopped as may be required.

In using the amalgamator, the pot A is filled with quicksilver nearly tothe lower end of the funnel G and steam at about forty-pounds pressureis turned on through the pipe I. The

powdered ore or fine sand is then fed into the G, and steam and waterpipes I and K, of the steam-tight casingH, the foot B, and tapered block0 F, all arranged, as shown and de scribed, to operate as specified.
